To all whom it may concern.

a citizen of the United States, and a resi dent of Mendota, in the county of La Salle,

Be it known that'I. WILLIAM E. -BRELSFORD State of Illinois, have invented certain new and useful Improvements in Antiskid Devices, of which the following is a full, clear, and exact description, reference being-had to the accompanying drawing, formingpart of this specificatio I My invention relates to deviceswhich are a which chains may be attached, the chains passing over thetire after the usual manner One object of my invention is to provide adevice which may be easily and quickly attached to the wheel structure, and which may also be easilydetachedtherefrom, and which will not injure the finish or appearance of the parts tojwhich it has been attached.' a

Anotherv 'objectof my invention is the provision of a simple and substantial means for attaching the cross-chains to the device, and for detaching them therefrom, when desired. 7

Other objects of my invention will appear and be described in the specification.

The novelty of my invention will be here inafter more fully set forth and specifically pointed out in the claims.

'In the accompanying drawing Figure 1 is a side elevation of a portion of an automobile wheel showing my device attached thereto.

Figure 2 is an end view of Fig. 1.

Figure 3 is a plan view of Fig. 1.

Figure 4 isa side view of a portion of the device showing some of the parts in a" different position from that shown in Fig. 1.-

Figure 5 is a plan view of the bracket portion of the device, showing the same detached from the wheel andextended ready for reattachment. r V

The same numerals of reference are used to indicate identical parts in all the figures;

In its preferred form of construction my invention comprisesa bracket portion 1 and preferably connected to the main member by Specification Letters'Patenti .,.Pa,tentgd. Apr, 1-1, 1922, Application filed-February 19, 1920. 'Seria1 N o. 359,816."

portion of the main member which extends betweenthe two spoke-engaging portions being preferably formed somewhat after the fashion of a channel iron with an upstand ing-"ce'ntral rib which is offset atitscenter, the flange and web of the channel being cut away on opposite sides at opposite ends'as shownin Fig. 5, the auxiliary members5 being-so formedas to'fil'l the places cutaway fro'rnfthe main members and complete. the channel section j when theauxiliary members are in the positions they occupy when the device isattached to the wheel". i

. The main member& is provided with turn buttons 9 which pass through suitably shaped openings'lO in the auxiliarymembers and a which, whenturned, after the auxiliary members are in proper position, 'hold and I "lock. these members 1n place.

The interior surfaces of themainiand so auxiliary members, or those surfaces which I come in contact with'any portion ofthe wheel when the device is attached'thereto,

are provided with afelt or other suitable Vi lining 18 to prevent injury to' the wheel structure during the use ofthe device, and

this lining may be held in place by any suit- V able meanssuch as rivets 11, though these linings may-be cemented or otherwiseheld in place. I

The spoke engaging portions of the main member 4 each carry an eye or loop 12 which is adapted to receive one of the hooks 3. to

the cross-chains 2, and each auxiliarymem- Lber carries a tension device which comprises a bell-crank 13 which i is; pivotally .mounted asat 14 to theauxiliary member, and which 7 carries .an eye or loop'15, similar to the loops 12 previouslydescribed and-adaptedto receive one ofthe hooks 3 of the cross-chains '2. Each'of the bell-cranks 13 is perforated as at 16 to pass-over aturn-buttonl'? car- 7 ried by the auxiliary member 5. The connection of the bell-crank 13 to the auxiliary;

member 5 is suificiently loose to permit the endwhich carries the'perforation16 to be position shown in Fig, 4, so that after one of the hooks 3 has been engaged with the loop 12, the hook on the opposite side of the cross-chain may be engaged with the loop 15 of the bell-crank 13, after which the bellcrank may be moved to a position where its perforated end may be moved to a position where its perforated end may be engaged with the turn-button 17, which movement will take up the excess length of the crosschain and hold it in proper operating relation to the tire of the wheel after which the turn-button 17 is turned to hold the bellcrank 13 in the position shown in Fig. 1.

To release the cross-chain it is only necessary to operate the turn-button 17 to release the bell-crank 13 after which it may be removed to the position shown in Fig. 4, and the cross-chain unhooked, whereupon if it is desired to remove the bracket portion of the device from the wheel the turn buttons 9-may be operated to release the auxiliary members 5 and the bracket portion removed from the wheel, though if desired the bracket portion of the device may be left 'on the Wheel, the bell-crank 13 reengaged with the structure.

turn-button 17 so that when it is desired to again attach the crosschains, they may be attached as previously described.

Having thus fully described my invention I claim: I

1. In an anti-skid device the combination oi a spoke and i elly engaging member comprising oppositely arranged spoke and felly engaging, portions, a pair of duplicate clamping members oppositely arranged and carried by the spoke and telly engaging member, and means for clamping the latter members in engaging position on a wheel 2. In an anti-skid device the combination of a spoke and telly engaging member provided with oppositely arranged spoke and telly engaging portions, a clamping mem ber hinged to each end of the spoke and telly engaging member, a pair of turn buttons carried by the spoke and telly engaging member, one of which engages each or" the clamping members, and a cross chain carried by the device and passing around the tread of the tire of the wheel structure,
